System-specific DDR4 upgrade for Lenovo IdeaPad 320

This 16 GB DDR4-2400 SODIMM is built for the Lenovo IdeaPad 320-17AST, 320-17ABR and 320-15ABR. It targets owners of those laptops who need the maximum single-module capacity the platform accepts. The module is non-ECC, unbuffered and runs at 1.2 V.

Single-stick kit with lifetime manufacturer exchange

The package contains one 260-pin stick rated CL17-17-17 at PC4-19200. Computer Memory Solutions guarantees compatibility with the listed models and backs the module with a limited lifetime exchange or repair warranty against manufacturing defects when purchased directly from the brand. No heat spreader is fitted.

DDR4 SO-DIMM slot and voltage ceiling

The laptop provides a single DDR4 SO-DIMM slot limited to 1.2 V operation. Faster DDR4 modules will down-clock to 2400 MHz; higher-voltage sticks will not function. The platform maximum is 16 GB, so this module fills the only slot and reaches the capacity ceiling.

Questions about this item

Will the 2Rx8 rank configuration require any future maintenance or replacement?

The 2Rx8 rank is a fixed hardware characteristic of this 16 GB DDR4 module and does not create any ongoing maintenance or replacement need.

What limit appears first during sustained use with the CL17 timing?

The CL17 CAS latency and 1.2 V operating voltage define the module's performance envelope; the memory controller's thermal or timing limits will be reached before the module itself degrades.

How much heat or power does the 1.2 V unbuffered SODIMM produce when running all day?

At 1.2 V the module draws minimal power and generates low heat, so it adds negligible thermal load inside a Lenovo IdeaPad 320 chassis during continuous operation.
